How the World’s Whitest Paint Can Reduce Energy Use

Posted on March 7, 2024 by dishanth

Scientists have long understood the climate and energy efficiency benefits of reflective white paints. Now, engineers at Purdue University have created the world’s whitest paint that reflects more than 98% of sunlight, leaving all other paints appearing grey by comparison. As demand for sustainable solutions grows globally, this innovation promises greener buildings and cities by passively lowering carbon emissions and energy use.

The world’s whitest paint formulation was reportedly completed in early 2021. While initially produced for research applications at Purdue, press releases indicate Perdue intends to optimize and commercialize the product for widespread availability as early as late 2023. This rapid early adoption timeline speaks to the hunger for market-viable incremental gains in cooling efficiency as global temperatures continue rising.

With the formulas and methods published openly, it remains to be seen whether alternate whitest paint variants may emerge from other research teams or commercial producers, sparking a global race toward passive cooling innovation. Even moderate cooling boosts from white paint could incentivize entities like major cities to begin budgeting for wide-scale reflective surface projects within the decade.

Applying the world’s whitest paint to building rooftops and envelopes can reduce their surface temperatures by over 20°C compared to conventional options. By reflecting rather than absorbing heat, the broad deployment of the world’s whitest paint could mitigate the phenomenon of urban heat islands, where dense cityscapes absorb and radiate increased warmth. Modeling suggests summer city temperatures could decrease by over 2°C using this approach.

The development of a highly reflective and renewable calcium carbonate-based paint offers an innovative solution to excessive urban heating. As climate change brings more frequent and intense heat waves, the cooling potential of reflective white surfaces will grow increasingly impactful. Deploying this paint across a city’s building stock can lower indoor and outdoor temperatures while cutting air conditioning demands as well. Transitioning rooftops from heat-trapping dark colors to the whitest paint formula could become a climate resilience strategy for communities worldwide.

Looking beyond buildings, custom reflective paints and paving materials show similar potential for cooling everything from vehicles to sidewalks to transit shelters. An urban landscape covered with maximum heat reflection could compound cooling benefits compared to white rooftops alone. More research into expanding high-albedo surfaces across the built environment will further quantify the associated quality of life and emissions reductions. Simple shifts in surfaces and materials at scale could make future cities markedly more livable.

The world’s whitest paint keeps surfaces cool to the touch, even in the hottest environments. Compared to the air temperature at mid-afternoon, a surface painted with the world’s whitest paint can be several degrees cooler than regular white paint. At night, the difference is even more pronounced, up to 19 degrees.

The corresponding drop in air conditioning electricity demand is equally significant from an emissions reduction perspective. Studies by the US Environmental Protection Agency show cool roofs can reduce a building’s annual air conditioning requirements by 10-30%. The increased grid energy efficiency will provide critical flexibility for integrating renewable energy sources as part of essential decarbonization efforts across the power sector.

While the world’s whitest paint’s exceptional solar performance will justify further optimization before mass production, its imminent commercial arrival heralds a shift in leveraging incremental materials innovation. The compound benefits of collective small-scale action represent meaningful progress, offering pragmatic climate hope. If cool paint alone makes summers more bearable, our combined creative efforts focused first on the possibly more than the ideal may yet brighten prospects for sustainable living.

With vision and patience, Perdue’s ultra-white paint is but a glimpse of a future where green cities are dotted with communities that thrive in the hotter world they’ve warded off, one roof at a time.

Meta Powers Towards Net Zero with Carbon Removal Projects

Posted on February 7, 2024February 7, 2024 by dishanth

Any organisation worth their sustainability salt knows that reaching net zero emissions in operations alone is not enough

Decarbonization must extend beyond offices and factories to include Scope 3, from the emissions caused by suppliers to those created by employees.

For Meta, the world’s fifth-biggest tech company, this challenge is being met with ambitious targets and bold, meaningful action.

Having already hit net zero emissions in global operations in 2020, the social media giant now has its sustainability sights set on achieving net zero value chain emissions by 2030.

This is quite the challenge, given 99% of Meta’s carbon footprint came from Scope 3 in 2022 – and this continues to rise.

“We know that reaching net zero emissions across our value chain will not be an easy task,” Rachel Peterson, Vice President of Data Centre Strategy at Meta said in the company’s 2023 Sustainability Report.

“Right now, our Scope 3 emissions are increasing and will continue to do so as we work to support the global demand for the services we provide.”

Meta Tackles Hard-to-Abate Sectors with Carbon Removal Projects

Meta acknowledges that reaching this goal requires a significant shift in how it builds infrastructure and operates its entire business – and the 20-year-old company is prioritising efficiency and circularity in its business decisions and embracing low-carbon technology to operate with a lower emissions footprint.

For example, through its supplier engagement programme, Meta is working to decarbonise its supply chain and enable at least two-thirds of its suppliers to set SBTi-aligned reduction targets by 206.

However, there are some emissions from hard-to-abate sectors the Facebook owner knows will be difficult to reduce by the end of the decade.

And so to tackle this, Meta has turned to carbon removal projects, the third pillar in its high-level emissions reduction strategy.

In a white paper outlining its Net Zero Strategy, the company says investing in value chain emissions reductions projects is necessary to address sources it can’t directly influence – like companies or processes used to extract and process the copper in data centre hardware or mechanical electrical equipment.

“These projects offer a significant opportunity to decarbonise our business at pace and scale require to achieve our 2030 reduction target,” the paper states.

For Meta, a diverse approach to carbon removal that includes both nature-based and technological approaches is crucial – not only to ensure near-term climate impact but to support carbon removal solutions for the future.

This strategy involves the purchase of credits from projects that align with Meta’s principles, from reforestation to investment in direct air capture technology.

Nature-Based Solutions in Mitigating Carbon Emissions

Since 2021, the social media giant has supported numerous nature-based carbon removal projects, from Australia to Kenya, including increasing forest carbon stock of community ejido forests in Oaxaca and increasing stored carbon via protection of forests that provide habitat for mitigating salmon in California.

And demonstrating its continued commitment to investing in nature-based solutions to mitigate carbon emissions, Meta recently signed a major carbon credits deal for 6.75 million carbon credits with Aspiration, a leading provider of sustainable financial services.

These credits hail from a myriad of ecosystem restoration and natural carbon removal approaches, including native tree and mangrove reforestation, agroforestry, and the implementation of sustainable agricultural practices.

Meta’s role in the voluntary carbon market extends beyond purchasing credits from projects to supporting new project development through financing and encouraging the evolution of standards that bring more certainty to the market.

Among the ways Meta is driving development in the sector is through collaborative action that will “aggregate the resources of multiple companies to create rapid change at scale”.

This includes a collaborative pledge to develop carbon projects that centre Indigenous leadership.

Through 1t.org, the National Indian Carbon Coalition and Meta have pledged to support and promote a model of carbon projects that centre on the leadership, traditional ecological knowledge, and vision of Indigenous Peoples for themselves and their land.

Among other collaborative projects:

Participation in the Business Alliance to Scale Climate Solutions (BASCS), which provides a platform for businesses and climate experts to meet, learn, discuss and act together to improve climate solutions.
Collaboration with the World Resources Institute to develop a method to map forest canopy height↗ at individual tree-scale using a new Meta AI training model. We have mapped forest canopy in California and São Paulo, Brazil, and are making the data public and freely available

Meta’s Role in Scaling Carbon Removal Technologies

In further driving development in the sector, Meta joined forces with other big tech companies in 2022 to accelerate the development of carbon removal technologies by guaranteeing future demand.

While some say focusing on carbon capture is a distraction to the real goal of reducing greenhouse gas emissions, Meta argues that both emissions reductions and carbon dioxide removal are needed.

And climate science backs this up.

Scientists say removing the carbon emissions that we have already pumped into the atmosphere is necessary if we are to avoid the 1.5-degree rises in global temperature set out in the Paris Agreement.

Launched in 2022, Frontier is a US$925 million joint commitment between Meta, Stripe, Shopify, McKinsey Sustainability and Alphabet – more recently bolstered with four new companies – Autodesk, H&M Group, JPMorgan Chase and Workday – committing a combined US$100 million.

Frontier helps its member companies purchase CO2 removal via pre-purchase agreements or offtake agreements. The goal is to spur the development of a new industry by providing a novel source of funding that isn’t based on debt or equity investments, but on actual product purchases before the technology is fully available at scale.

So far, Frontier has spent $5.6 million buying nearly 9,000 tonnes of contracted carbon removal from 15 different carbon dioxide removal startups.

Among these, RepAir uses electrochemical cells and clean electricity to capture carbon dioxide from the air, while Living Carbon is a synthetic biology startup working on engineering natural systems to remove carbon dioxide.

With this strategy, Meta is helping to expand the voluntary carbon market, overcome barriers to scale, and at the same time achieve its own ambitious net zero goals.

How manufacturers can transition to 100% renewable electricity

Posted on January 3, 2024 by dishanth

Manufacturing and other industrial users account for around a third of the world’s energy consumption, according to the International Energy Agency(1). Electricity is a central element of that. If all the power consumed by factories and industrial plants came from renewable sources, it would make a sizeable contribution to tackling climate change.

It is a tough target, but one that companies are increasingly signing up to. The RE100 initiative, for example, has seen more than 400 corporations commit to 100% renewable electricity use across their operations. How they reach that goal will depend on many factors, including what they are making and where.

Switching to renewable electricity

“Organisations with lighter electricity needs and stable finances will be best positioned to transition to renewables. Companies with high electricity demand, like furnaces for glass, smelting or other large-scale heating applications and companies with very large footprints – such as expansive warehouses and assembly operations – may have more difficulty,” says Paul Holdredge, Director for Industrials and Transport at consultancy Business for Social Responsibility (BSR).

COP28 president-designate Dr Sultan Al-Jaber told the Adipec conference in Abu Dhabi in early October(2) that heavy industries may be hard to decarbonise but added “We know that solutions exist, and all industries can and must respond.”

The prospect of switching to renewable electricity has become far easier due to recent dramatic cost reductions. According to the International Renewable Energy Agency (IRENA), the price of solar photovoltaic power in 2010 was typically 710% higher than the cheapest fossil fuel, but by 2022 it was 29% cheaper(3). Currently electricity accounts for around 20% of final energy use in manufacturing, according to the International Renewable Energy Agency, and this is only expected to increase.

The manufacturing challenge

But it is not just the price of renewable energy, low as it is, that dictates a manufacturer’s ability to move to 100% renewable energy. Both the required initial capital investment and first-mover disadvantage—where it costs pioneers more than those that follow them to deploy new technologies—can significantly slow down a fully renewable transition. Not to mention the lack of availability of certain renewables in certain geographies and the fact that the appropriate infrastructure must be in place for this energy to be delivered—something no one company can do on its own.

Manufacturing requires an enormous amount of electricity in comparison to offices. In some countries or regions where the supply of renewable electricity is limited, like Japan, Taiwan, and Singapore, it is much more expensive than electricity produced by traditional means, placing a significant future cost burden on companies that purchase renewable electricity.

Epson is working to popularize the use of renewable electricity, despite the certainty of short-term cost increases. The company is advancing investment in sustainability to enrich communities and invest in future generations to create social value.

Going local

Wherever they are in the world, with whatever types of renewable energy available to them, companies need to adapt to local, national, and global circumstances. Seiko Epson, based in Japan, has done just that. Having switched to 100% renewable electricity for all its sites in Japan in 2021, it will complete the transition to 100% renewable electricity globally by the end of 2023(4). This goal has been made achievable through steady implementation of decarbonization targets and the use of renewable electricity since 2018.

In Nagano Prefecture, Japan, for example, where water sources are abundant, it relies on hydroelectric power. But in the Tohoku area, where it has a semiconductor fabrication plant, it uses hydropower and geothermal heat from the Ou mountains.

It is taking a similar approach outside Japan. In the Philippines, it taps into local geothermal and hydroelectric sources. While in Indonesia, it uses yet another renewable source—biomass power.

“We have used locally produced energy wherever possible,” says Junichi Watanabe, Managing Executive Officer General Administrative Manager, Production Planning Division, whose role encompasses the promotion of Epson’s procurement strategies in the supply chain, including the use of renewable electricity. “Rather than using energy generated in faraway countries, using a particular region’s abundant renewable resources brings many benefits, such as improving energy self-sufficiency and creating jobs.”

In addition to purchasing renewable electricity, Epson co-creates and develops other power sources through continuous renewable electricity purchases. In partnership with Nagano Prefecture and Chubu Electric Power Miraiz Company, Inc., the company began support of hydroelectric power plants in Nagano Prefecture. Two are already in operation (totalling 5,770 kilowatts) and another is scheduled to begin operation in 2024. That number is expected to increase to five by 2025.

Such targets can help a company stand out from the crowd. “Based on our research, setting a near-term goal for 100% renewable electricity use is an example of leadership and a differentiator. Some companies also have roadmaps to transition over longer time periods,” says Holdredge.

Among the practical methods companies should consider are:

• Sourcing renewable electricity from local suppliers via contracts with electricity suppliers – the ability to do this will depend on the rules in a particular country but, if it is possible, a company can be confident its electricity is only coming from renewable sources.

• Generating electricity on-site, via rooftop solar panels or, if space allows, wind turbines. Even if they do not generate all the power needed, they can still make a useful contribution.

• Develop battery storage facilities. A common concern about renewable electricity is the risk of supply being interrupted when the wind isn’t blowing or the sun isn’t shining, but storage technology offers a viable way to address that.

When it comes to solar power generation systems, Epson’s sites also decide whether to adopt self-investment or power purchase agreement (PPA) based on the individual circumstances of each country or region. The solution will vary from company to company. But most manufacturers are likely to find a combination of these elements will go a long way to reaching their renewable electricity goals.

What’s more, many manufacturers like Epson realize that their indirect GHG emissions from their entire value chain (Scope 3) are much greater than the GHG emissions from their own electricity use (Scope 2). As such, by reducing the sector’s Scope 2 emissions using renewable energy—something the sector can do independently—is likely to have a far greater impact on society. Setting goals early and demonstrating a company’s stance toward solving climate change is the key to co-prosperity with suppliers and a sustainable society.

“For large companies the return on investment is there to make the case for investment in renewables. For smaller companies this can also be true, but it depends on the geography. Government incentives can only speed up transition which is sorely needed,” says Christy Slay, Chief Executive Officer of The Sustainability Consortium.

The future for greener manufacturing

There are big gains for humanity if climate change can be addressed, but for manufacturing companies and their shareholders the best approach could also deliver commercial gains.

Consumers and investors are increasingly likely to reward companies with greener credentials, making it an essential part of long-term market positioning. In addition, greater use of renewables and greater self-generation can make a company more resilient to volatile electricity prices on the open market.

“Reaching 100% renewable is tough but pushing to get as close as possible, as soon as possible should be every company’s focus right now,” says Slay. “Epson has managed to stay one step ahead of the industry and is setting an example not only to Japan but to the world.”

Larger Cargo Bikes in NYC Transport More Goods

Posted on December 6, 2023 by dishanth

City is considering larger cargo bikes in NYC to transport more goods in more places.

New York City may soon permit larger cargo bikes in NYC to legally operate on its streets in a move that could substantially grow urban freight delivery by cycling. The NYC Department of Transportation proposed new rules that would legalize pedal-assisted electric cargo trikes up to 10 feet long and 10 feet high.

If adopted, the larger trike dimensions would enable more goods to be transported by bikes rather than vans and trucks. Advocates say embracing cargo bikes tailored for commercial uses can reduce traffic, pollution, noise, and curbside congestion caused by urban delivery vehicles.

Under current regulations, only smaller cargo bikes meeting dimensions for standard bicycles are street-legal in NYC. Larger cargo bikes in NYC are all but inevitable; cargo trikes exceeding those size limits have become popular for urban logistics in other US and European cities.

The proposed guidelines for larger cargo bikes in NYC would align with size allowances for cargo trikes in cities like Seattle, Detroit, and Philadelphia. The NYC DOT stressed cycling freight remains supplementary to traditional truck delivery but offers environmental benefits.

Larger cargo bikes in NYC can “provide increased hauling capacity compared to smaller bicycles…potentially reducing reliance on truck trips and promoting a more sustainable city,” the agency stated.

Expanding cargo bike delivery supports sustainability goals in New York City’s 25-year master plan released in 2021 aimed at equitable climate action. The plan’s transportation section calls for transitioning to cleaner freight options to reach carbon neutrality.

Advocates say allowing larger cargo bikes in NYC tailored for commercial uses would align with the master plan’s priorities. They argue substituting just one fossil fuel-powered delivery truck or van with an electric-assisted cargo trike prevents significant emissions over time. Each trike potentially displaces those larger, polluting vehicles that are worsening both congestion and air quality on NYC streets.

Wider cargo bike adoption can make a meaningful dent in transportation emissions, accounting for nearly 30% of New York City’s total carbon footprint. Cargo bikes also alleviate other pressures urban delivery vehicles create, such as noise, parking limitations, road safety concerns, and decreased public space. Unlocking the potential of micro-mobility freight options like cargo trikes is key to reaching the sustainability vision outlined in the 25-year plan.

The larger cargo bikes in NYC would utilize electric assist motors to haul substantial loads up to 500 pounds with minimal strain compared to pedaling those heavy full loads. Their three-wheeled stable design and sturdy hauling strengths make these cargo trikes ideal urban delivery vehicles for short distances or last-mile trips from distribution hubs. Cargo bikes’ small size, maneuverability, and zero direct emissions also let them nip through urban traffic easily for swift point-to-point goods movement.

Commercial cargo trike models can have front buckets or storage bins to securely transport goods, food orders, packages and more. Some designs allow custom boxes or refrigerated containers to be attached.

Logistics companies like Amazon, UPS, and FedEx already use cargo trikes in a few American cities to shortcut traffic in dense areas. Smaller NYC firms have recognized their benefits as well. For example, Gotham Greens, an urban produce grower, relies on a fleet of cargo bikes to distribute fresh salad greens to local restaurants and stores from their rooftop greenhouses. Beer distributor TriBeca deployed heavy-duty e-trikes last year capable of carrying 800 lbs of beer kegs to pubs and restaurants. They aim to replace several delivery vans to cut diesel emissions.

Experts say each switched delivery from vans to bikes eliminates, on average, about 7 tons of carbon dioxide emissions annually. Less truck traffic and parking also create safer, quieter streets.

But despite their promise, cargo bikes presently make up a tiny fraction of urban goods movement. Questions remain over whether larger cargo bikes in NYC could substantially dent air pollution and congestion woes created by the over 65,000 daily truck trips.

The NYC DOT will collect public feedback on proposed cargo trike regulations this spring before finalizing new rules. Customized trike manufacturers and logistics firms will be watching closely.

Larger cargo bikes have carved growing niches abroad in Amsterdam and London. For cycling advocates, allowing them in New York City could be a critical step to build momentum for sustainable urban freight.

Low Carbon 3D Printed Homes – Lower Cost too

Posted on November 23, 2023 by dishanth

An emerging application of 3D printing technology is fabricating entire homes through additive manufacturing. Early adopters demonstrate that 3D printing residential buildings carry significantly lower embedded carbon than conventional construction methods.

By optimizing materials and printing processes, 3D home printing could provide affordable, efficient, low-carbon housing to growing populations if adopted at scale.

Also known as additive manufacturing, 3D printing builds structures by depositing materials layer by layer according to digital models. Concrete is typically extruded through a moving print nozzle onto a substrate, hardening upon deposition to gradually form walls and roofs of low carbon 3D printed homes.

Companies pioneering low carbon 3D printed homes include Icon, SQ4D, and Mighty Buildings. Their printed concrete or polymer designs streamline manual labor of framing, insulation, and finishing. Architectural designs are also easier to customize versus cookie-cutter manufactured units.

But the sustainability benefits are among the most significant advantages over current construction. Architect Sam Ruben, an early adopter of 3D printing for eco-homes, states that 3D printing can reduce lifecycle emissions by over 50% compared to standard building techniques.

Part of the savings comes from more efficient material usage. Conventional construction methods are wasteful, generating excessive scrap materials that go to landfills—3D printing deposits only the needed amount layer-by-layer, eliminating waste.

Printing also allows easier integration of recycled components like crushed concrete aggregate into prints, diverting waste streams. And lightweight printed structures require less embedded energy to transport modules. Optimized print geometries better retain heat as well.

But the biggest factor is speed – printed homes can be move-in ready in days rather than weeks or months. A standard SQ4D home prints in just 8-12 hours of machine time. Accelerated production means less energy consumed over the total construction period.

And speed has financial benefits, too, reducing the logistical costs of prolonged projects. Combined with simplified labor, 3D printing can cut estimated construction expenses up to 30%. Those cost savings make printed homes more accessible to low-income groups while stimulating large-scale adoption.

To quantify benefits, Mighty Buildings completed a life cycle assessment comparing their printed composite polymer dwellings against conventional homes. They estimated their product cut emissions by over one-third during materials and construction. Waste production dropped by over 80%.

Such data helped the company achieve third-party verified EPD declarations certifying their low carbon 3D printed homes. Mighty Buildings believes printed homes could eliminate over 440 million tons of carbon emissions if comprising 40% of California’s housing needs by 2030.

Despite advantages, barriers remain to limit widespread 3D printed housing. Printed buildings still require finishing like plumbing, electrical, windows, and roofing. Developing integrated printing around and including those elements will maximize benefits.

High upfront printer costs also impede adoption, though expected to fall with scaling. And building codes need updates to cover novel printed structures despite proven duribility. Some jurisdictions like California are pioneering efforts to add low carbon 3D printed homes as approved models in housing codes.

But if technical and regulatory hurdles are resolved, additive construction could offer meaningful emissions cuts. With global populations projected to add 2 billion new urban dwellers by 2050, low carbon 3D printed homes may become a go-to sustainable building technique, especially in growing developing countries.

The urgent need for dense, low-carbon housing solutions to accommodate global populations makes 3D printing’s advantages stand out. Printed homes advance from gimmick to viable strategy against climate change.

Eco-conscious homebuyers on a budget have a new choice – low carbon 3D printed homes made from low-carbon cement. A new housing tract in Round Top, Texas has introduced small dwellings printed using concrete that produces just 8% of the carbon emissions of traditional Portland cement manufacturing.

Habitat for Humanity last year unveiled its first low carbon 3D printed home in Williamsburg, Virginia. The project represented Habitat for Humanity’s first completed 3D printed home in the country.

By combining 3D printing techniques with more sustainable cement mixtures, homebuilders can reduce the carbon footprints of affordable printed housing even further.

New Carbon Capture Tech Turns CO2 into Solid Carbon

Posted on November 8, 2023 by dishanth

New capture technology turns CO2 into solid carbon, a coal-like product that can be safely reburied.

Scientists may have discovered a groundbreaking new method to pull out of the air and convert CO2 into solid carbon flakes. Researchers at Australia’s Royal Melbourne Institute of Technology (RMIT) have pioneered an efficient carbon mineralization process using liquid metal catalysts. This technology could provide a sustainable way to capture atmospheric CO2 and safely store it long-term as a stable solid.

Most carbon capture techniques today focus on compressing CO2 gas into a liquid that is injected deep underground. However potential leakage risks make this method less than ideal for permanently storing billions of tons of carbon dioxide. We urgently need innovative solutions to remove and safely store the CO2 already overburdening our atmosphere.

That’s why RMIT’s new mineralization approach to turn CO2 into solid carbon is so promising. It converts greenhouse gases into inert carbon solids at room temperature. This offers a potentially cheaper, more secure form of carbon storage compared to current methods.

RMIT’s method utilizes molten liquid metals to trigger a chemical reaction, transforming gaseous CO2 into solid carbon flakes. This occurs at ambient temperature inside a simple glass tube device. The process works by sending CO2 into the glass tube containing a liquid metal alloy of gallium, indium, tin, and cerium. Running an electric current through the metal accelerates the carbon mineralization reaction.

Carbon steadily accumulates as a layer of solid flakes on the liquid metal surface and the only byproduct of the process is pure oxygen. The flakes are then removed allowing the process to continue indefinitely. Because this process occurs are room temperature, the energy requirements are far lower than other systems.

The researchers experimented with different metal compositions and temperature conditions to optimize the carbon conversion process. Once optimized, the system can continuously pull in and convert atmospheric CO2 into solid carbon without additional heat or pressure.

Unlike underground injection techniques, solid carbon can easily be collected for safe, permanent storage. The carbon solids could even be processed into materials like carbon fiber. And since the process only needs a small amount of electricity and air, it has minimal environmental impact or manufacturing costs.

Turning CO2 into solid carbon could be a more predictable, sustainable and longer lasting approach to carbon capture and storage. The RMIT team is already investigating ways to scale up the liquid metal carbon mineralization method. Adoption by power plants or heavy industry could significantly cut CO2 outputs.

Finding viable ways to remove excess greenhouse gases is critical to slow global warming. Since the Industrial Revolution, over 1.3 trillion tons of carbon dioxide have entered the atmosphere – and the pace is accelerating. New solutions like RMIT’s carbon mineralization technology will be essential to extracting legacy emissions already dangerously heating our planet.

Harnessing Carbon Mineralization: A Powerful Tool to Combat Climate Change

Posted on September 8, 2023 by dishanth

Carbon mineralization, the process that converts carbon dioxide into solid carbonate minerals, holds immense potential to combat climate change. While it occurs naturally, humans can accelerate this process through various methods.

By refining techniques such as biochar utilization, enhanced weathering, and ocean fertilization, we can unlock the power of carbon mineralization to effectively reduce atmospheric carbon dioxide levels and mitigate the adverse impacts of climate change.

There are many ways in which we can accelerate the amount of carbon we sequester using the process. Biochar, a form of charcoal derived from biomass, offers a sustainable solution to enhance carbon mineralization. When integrated into the soil, biochar amends its composition, enhancing its capacity to sequester carbon. The porous structure of biochar acts as a long-term reservoir, promoting carbon retention while fostering beneficial microbial activity in the soil. This method bolsters soil fertility and carbon storage, contributing to climate change mitigation and sustainable agriculture.

Enhanced weathering harnesses the natural process of rock breakdown to expedite carbon mineralization. Techniques involve accelerating rock weathering by introducing acidic or basic substances or fragmenting rocks into smaller particles. Carbon dioxide reacts with the minerals, forming stable carbonate compounds that can endure for centuries. By leveraging enhanced weathering, we can significantly augment carbon sequestration rates, offering a tangible solution to counteract rising carbon dioxide levels.

Ocean fertilization presents a compelling avenue to store carbon on a large scale. By introducing essential nutrients, such as iron or phosphorus, to the ocean, the growth of algae is enhanced. These algae act as carbon sinks, absorbing atmospheric carbon dioxide through photosynthesis. Subsequently, when the algae die and sink to the ocean floor, they carry the sequestered carbon along, where it can remain locked away for centuries or even longer. Ocean fertilization holds promise in its ability to mitigate climate change while fostering marine ecosystems.

Carbon mineralization represents a powerful tool in the fight against climate change, offering several noteworthy advantages over other methods:

Substantial Carbon Removal: By accelerating carbon mineralization, we can remove billions of tonnes of carbon dioxide from the atmosphere annually. This significant reduction in greenhouse gas concentrations would directly curb global warming and its associated impacts.
Leveraging Natural Processes: Carbon mineralization harnesses and enhances naturally occurring processes. By utilizing and accelerating these processes, we minimize the need for technologically complex and energy-intensive solutions, leading to a more sustainable approach to climate change mitigation.
Restoration of Carbon Balance: Historically, human activities such as deforestation and fossil fuel combustion have disrupted the carbon balance by releasing large amounts of carbon dioxide into the atmosphere. Carbon mineralization offers an opportunity to restore this balance by actively sequestering carbon and reversing the damage caused by human-induced carbon emissions.

While carbon mineralization shows tremendous promise, these are early days. Implementing carbon mineralization techniques on a large scale requires substantial investment and infrastructure development. The costs associated with establishing and maintaining these methods may present challenges, necessitating collaborative efforts from governments, private sectors, and research institutions.

It is crucial to carefully assess the potential environmental impacts of carbon mineralization techniques. For instance, ocean fertilization may disrupt marine ecosystems if not executed responsibly. Thorough environmental impact assessments and regulatory frameworks are essential to ensure the sustainable deployment of carbon mineralization methods.

Carbon mineralization offers an innovative and promising approach to mitigating climate change by actively removing carbon dioxide from the atmosphere. Through methods like biochar utilization, enhanced weathering, and ocean fertilization, we have the potential to achieve substantial carbon sequestration, restore the carbon balance, and forge a more livable planet.

6 Types of Cool Roof Technology

Posted on August 15, 2023 by dishanth

Cool Roof Technology: a Low-cost Way to Reduce Energy Consumption and Carbon Emissions

Want a huge decrease in carbon emissions, a reduction in summertime cooling costs and a more efficient home? Cool roof technology can do all that. Cool roof technology has the potential to eliminate billions of tons of carbon dioxide at a very low cost.

If you’ve ever spent time on a black asphalt roof or up in an attic during the heat of summer, you understand how much heat energy is added to a home during summer months. This is heat that many of us pay to remove by using air conditioners and other means.

But what if, just by a better design and choice of materials, we could have a far cooler house that uses far less electricity each month? That is what people in the Mediterranean and other hot climates have been doing for centuries. White paint and chimney-style ventilation that distributes cool air from lower areas of the house are low-tech examples of cool roof technology that works.

Modern cool roof technology is similar. Most are just like regular roofs but are designed to reflect sunlight and shed heat, to keep buildings cooler in the summer. According to a study by the National Renewable Energy Laboratory (NREL), cool roof technology could reduce energy consumption for cooling by up to 20%. The study also found that energy savings from cool roof technology could eliminate up to 1.4 billion tons of carbon dioxide emissions annually in the United States. The equivalent of taking 300 million cars off the road!

According to Lawrence Berkeley National Laboratory, if all North American cities with populations over 1 million people adopted cool roof technology, air conditioner use would fall by one-third.

The Human Cost of Heat

The savings aren’t just in terms of money and carbon emissions. Climate change has disproportionately increased temperatures in urban areas. An urban landscape largely covered in asphalt, concrete and black roofing materials is far hotter than one covered in greenery or reflective materials, a phenomenon known as the urban heat island effect.

The urban heat island effect is the phenomenon of cities being warmer than surrounding rural areas. This is because cities have more dark surfaces, such as black roofs, which absorb sunlight and heat up the air. The heated air then rises, creating a convection current that draws in cooler air from surrounding areas. This process can lead to increased temperatures in cities, which can have a number of negative consequences, such as increased energy consumption for cooling, decreased air quality, and increased heat-related illnesses and deaths.

Black roofs also radiate energy directly into the atmosphere. This energy is then absorbed by clouds and trapped by the greenhouse effect, further contributing to global warming.

Type Depends on Location Climate

There are a number of different types of cool roof technology available, including:

Reflective roofs: Reflective roofs are the most common type of cool roof. They are made of materials that reflect sunlight, such as white or light-colored tiles, metal roofs, or paints. Reflective roofs can reflect up to 90% of the sun’s heat, which can help to keep buildings cooler in the summer.
Evaporative roofs: Evaporative roofs are made of materials that allow water to evaporate, such as clay tiles or metal roofs with a water-absorbing coating. As the water evaporates, it cools the roof and the building below. Evaporative roofs can be effective in hot, dry climates.
Phase-change materials: Phase-change materials are materials that change their state from solid to liquid and vice versa. When these materials change phase, they absorb or release heat. Phase-change materials can be used in cool roofs to store heat during the day and release it at night. This can help to keep buildings cooler in the summer and warmer in the winter.
Cooling paints: Cooling paints are paints that are applied to roofs to make them more reflective and to help them cool down. Cooling paints are effective in hot, sunny climates and typically contain titanium dioxide, a highly reflective pigment.
Cooling granules: Cooling granules are small, reflective beads applied to roofing materials like shingles. The granules reflect sunlight and help to keep the roof cooler. Like cooling paints, cooling granules are most effective in hot, sunny climates.

Green Roofs are Cool Roofs

Another type of cool roof technology is the green roof. Green roofs are made of a waterproof membrane with a layer of soil and vegetation on top that helps to insulate the roof and reflect sunlight. Green roofs can reflect up to 70% of the sun’s heat, which can help to keep buildings cooler in the summer. In some cases, they can provide vegetable gardens or just a nice place to sit and enjoy the feeling of being surrounded by nature – while in the city.

Green roofs also have the effect of providing bird and pollinator habitat as well as reducing stormwater runoff. Because of the benefits, many cities are now mandating the installation of green roofs on new construction. New York, San Francisco, Chicago, Seattle and Portland all require green roofs on new construction on buildings with roof areas over a specific set size. That said, retrofitting an existing building is often cost prohibitive due to the structural requirements to support the additional weight.

Cool roof technology is a promising way to reduce greenhouse gas emissions and improve the energy efficiency of buildings. As the technology continues to develop, the potential for cool roofs to reduce carbon dioxide emissions will likely increase.

This is an easy way to make big gains in carbon reductions, saving homeowners and businesses money. Something we can all get behind.

According To New Study, Dust Absorbed By Phytoplankton Benefits Them

Posted on June 7, 2023 by dishanth

Carbon prevention or carbon capture?

A significant amount of the conversation surrounding climate change concerns the release of carbon dioxide into our atmosphere. While this is important, the priority is most concerned with reducing or eliminating fossil fuel emissions.

While achieving this goal is paramount in creating a clean, eco-friendly world, the topic of carbon sequestration has been under the radar until recently. When most think of carbon sequestration, they imagine carbon capture and storage (CCS) technology or think of trees.

Both are valuable and productive carbon sequesters; however, they are not the only areas or mechanisms useful for reducing carbon dioxide in our atmosphere. Our world’s oceans are single-handedly the largest carbon sinks we have, and many marine organisms participate in this important process.

Phytoplankton makes up an important role in carbon deposition onto the ocean floor. In recent years, they have been thriving due to mass amounts of dust being created and deposited.

Carbon sinks and carbon eaters.

In the ocean, there are multitudes of different organisms sequestering carbon. Seagrass is one of the largest carbon sequesters and provides large habitats for other fish and marine animals to thrive in.

However, despite the outsize role that some marine organisms play in carbon sequestration, phytoplankton also makes up a key role.

Phytoplankton generally pulls up their nutrients from the ocean and use those nutrients to turn carbon dioxide into organic matter, which then gets deposited back onto the ocean floor.

Due to climate change-induced wildfires and natural disasters, phytoplankton have been thriving in recent years. According to a new study published in Science Magazine and led by Toby Westberry out of Oregon State University, there is a direct correlation between the amount of dust being brought into the ocean and the numbers and health of phytoplankton in the area.

They used satellite imaging to observe the differences in the coloration of the water before and after a major dust storm or wildfire occurred. They noticed that the water in the affected areas began to turn green, indicating larger numbers of phytoplankton.

The researchers also found that depending on the altitude of the marine environment, there is an observed difference in the health and numbers of phytoplankton. In lower altitude areas, there were fewer phytoplankton despite being healthy, and in higher altitude areas, there were more phytoplankton as well as being more healthy.

It all adds up.

Phytoplankton, while important, doesn’t make up as much of an impact on climate sequestration as one might hope. This is because dust-related phytoplankton growth only makes up 4.5% of the global yearly carbon dioxide absorbed by the ocean. Though, in some areas, the amount of carbon absorbed can reach highs of 40% of the total amount.

Nonetheless, It is important to be aware of the multitudes of different ways carbon sequestration can occur. These systems are large and complex and take up many different forms. To address the issue of storing carbon and removing it from our atmosphere, we must understand it won’t be a “one-size-fits-all” approach that is successful. It will take multiple different mechanisms working together and complementing each other to save our world. Phytoplankton, it seems, will be playing an important role in this.

Etihad Airways plans to use sustainable fuel made from CO2

Posted on May 19, 2023May 19, 2023 by dishanth

UAE-based airline Etihad Airways has partnered with Twelve, a carbon transformation company, to promote sustainable aviation fuel (SAF) produced from CO2 and renewable energy.

Twelve combines renewable energy and water to convert CO2 into vital chemicals and materials derived from fossil fuels. This innovative formula reduces lifecycle emissions by 90% compared to traditional fossil-based fuels and is compatible with current aircrafts.

Etihad’s sustainable mission

The new partnership aligns with Etihad’s sustainability goals of achieving net-zero emissions by 2050 and converting waste into fuel, with a target of diverting 75% of waste from landfills by 2025. The collaboration is driven by the growing demand for SAF among various airlines.

In 2019, the airline introduced the Etihad Greenliner Program, which allocated a Boeing 787-10 Dreamliner to focus on sustainability initiatives. The programme aims to identify and tackle key sustainability challenges through partnerships with Boeing and engine manufacturer GE.

SAF aligns with Etihad’s commitment to driving innovation and transforming the aviation industry towards sustainability, and the new partnership reinforces Etihad’s mission and sustainability efforts.

“Etihad Airways is working hard on its sustainability strategy and deploying a range of initiatives across the spectrum of sustainability to achieve that,” Mohammad Al Bulooki, Chief Operating Officer at Etihad said. “Collaborating with sustainable aviation fuel makers like Twelve to advance products like E-Jet fuel is an important part of that drive.”

A long-term solution for addressing aviation emissions

Twelve has developed a low-carbon jet fuel, E-Jet fuel, produced using carbon transformation technology, which has been tested and verified by the US Air Force.

By joining forces, the two businesses aim to plan international demonstration flights to promote SAF in the global market.

Twelve’s CEO, Nicholas Flanders, describes the partnership as an “honour” while highlighting the company’s progress towards a supply of drop-in jet fuel made from air and not oil.

Flanders continues: “Our E-Jet fuel allows airlines like Etihad to reduce emissions by up to 90% with their existing aircraft fleet, which will be critical to achieving the United Nations’ 2050 net-zero emissions target in aviation.”
